OCN EXAM 3 ONCOLOGY CERTIFIED NURSE QUESTIONS WITH
VERIFIED ANSWERS & RATIONALES (COMPLETE EXAM PREP
MATERIAL)
The symbiotic relationship between the coral animals and the zooxanthellae is an example of -
CORRECT ANSWERS-mutualism
The primary producers in chemosynthetic vent communities are - CORRECT ANSWERS-archaea
Recent studies indicate that the deep biosphere, an environment that exists within the seafloor itself,
may account for up to _________ of Earth's total bacterial biomass. - CORRECT ANSWERS-two-thirds
Of the following statements about benthic organisms, which is/are true? - CORRECT ANSWERS-
TRUE:Many benthic organisms spend the first part of their lives in the pelagic environment.
The vast majority of benthic species live on the continental shelf.
High abundances of benthic organisms are found beneath surface waters with high primary productivity.
FALSE:All benthic organisms are sessile (permanently attached to the ocean floor).
Benthic organisms cannot live beneath the euphotic zone.
Geologic evidence suggests that eustatic (global) sea level rises have been caused by - CORRECT
ANSWERS-rapid seafloor spreading at divergent plate boundaries
You own a beachfront lot that has been experiencing erosion due to beach starvation. Your neighbor to
the north (up-current) has the same problem, so he gets permission to build a groin just north of your
property line. Your response would probably be to - CORRECT ANSWERS-get permission to build a
groin of your own near the southern boundary of your property; A groin will help by trapping some of
the remaining sand from the longshore drift. However, it will only make the problem worse for down-
current properties
The coastal wetlands of Louisiana are being lost primarily because of - CORRECT ANSWERS-a
combination of subsidence and rising sea level
,Of the following statements about coastal regions and landforms, which is/are true?
The area of a beach above the shoreline is often called the recreational beach.
The berm is affected by storm waves but is typically dry and relatively flat.
The berm is located in the backshore area.
The nearshore is exposed during low tide each day.
Most of the beach face is exposed during the lowest tides and covered during the highest tides.
The beach face is the wet, sloping surface in the foreshore area. - CORRECT ANSWERS-The area of a
beach above the shoreline is often called the recreational beach.

The beach face is the wet, sloping surface in the foreshore area.
Of the following statements about longshore transport (longshore drift), which is/are true?
Longshore transport can change direction depending on which direction the waves approach the beach.
Longshore transport moves sediment in a zigzag path.
Longshore transport moves sediment upcoast or downcoast along the beach.
Longshore transport and rip currents are the same thing.
Longshore transport moves just a small amount of sediment along the shore during a year.
Longshore transport describes the movement of water in the surf zone. - CORRECT ANSWERS-
Longshore transport can change direction depending on which direction the waves approach the beach.
Longshore transport moves sediment in a zigzag path.
Longshore transport moves sediment upcoast or downcoast along the beach.
Of the following characteristics or features, which is/are associated with erosional shores?
, A large volume of sediment input
Tectonic activity
Wave-cut benches and marine terraces
A coastline with lots of rugged headlands
Rocky coasts - CORRECT ANSWERS-Tectonic activity
Wave-cut benches and marine terraces
A coastline with lots of rugged headlands
Rocky coasts
Of the following characteristics or features, which is/are associated with depositional shores?
Bay-mouth bars
The formation of barrier islands
A large sand spit
High sediment supply
A location near a large delta
Active tectonic uplift - CORRECT ANSWERS-Bay-mouth bars
The formation of barrier islands
A large sand spit
High sediment supply
A location near a large delta
Of the following statements about global sea level, which is/are true?
Sea level has risen about 120 meters (400 feet) in the past 18,000 years.
When seawater warms, it thermally expands and occupies more volume, so global sea level rises.
Sea level is affected by the amount of ice in polar ice caps on land.
When seawater cools, it contracts and occupies less volume, so global sea level is lowered.
